When cutting curves, make sure not to tilt the
power tool laterally and work with low feed rate
only.
For internal cuts a pilot hole of 15 mm (blade for
straight cuts) or 8 mm (blade for curved cuts) is
necessary.
Maximum Steel Sheet Cutting Capacity
The maximum steel sheet cutting capacity d
depends on the strength properties of the mate-
rial to be cut.
The machine allows for cutting of metal sheet to
the following thicknesses:
Material
Blade for straight cut
Steel
Aluminium
Blade for curved cut
Steel
Aluminium
Lubricating/Cooling the Cutters
In order to extend the lives of blade and cutter
bar you should use a lubricant with a good cool-
ing capacity (e.g. cutting oil).
Apply a trail of lubricant beads onto the top side
of the metal sheet alongside the intended cutting
line. For long periods of continual use or for work
with high frictional wear (e.g. when cutting alu-
minium), the cutting head should be immersed
into a container with lubricant in regular inter-
vals.
